XOOPS模組開發
=========

1. 先編輯樣板，根據身份加入「編輯」按鈕 ```
  <pre class="brush:xml;gutter:false;">
  <td>
    <{if $isAdmin}>
      <a href="admin/main.php?action_id=<{$action.action_id}>" class="btn btn-warning btn-xs">編輯</a>
    <{/if}>
    <a href="index.php?action_id=<{$action.action_id}>" class="btn btn-info btn-xs">詳情</a>
  </td>
  ```
2. 接著編輯 admin/main.php，修改一下其流程，因為有傳入 action\_id 的變數進去，表示要修改該資料內容了。
  
   ```
  <pre class="brush:php;gutter:false;highlight:[4,15];">
  /*-----------執行動作判斷區----------*/
  include_once $GLOBALS['xoops']->path('/modules/system/include/functions.php');
  $op        = system_CleanVars($_REQUEST, 'op', '', 'string');
  $action_id = system_CleanVars($_REQUEST, 'action_id', 0, 'int');
  try
  {
      switch ($op) {
  
          case "insert_action":
              $action_id = insert_action();
              header("location: ../index.php?action_id={$action_id}");
              exit;
  
          default:
              action_form($action_id);
              break;
      }
  } catch (exception $e) {
      redirect_header($_SERVER['PHP_SELF'], 3, $e->getMessage());
      // $xoopsTpl->assign('error', $e->getMessage());
  }
  include_once 'footer.php';
  ```
3. 最重要的是修改原來的表單函數，針對編輯狀態要多加一些動作：
  
   ```
  <pre class="brush:php;gutter:false;highlight:[2,8,9,10,11,12,14,14,16,17,41,42];">
  //顯示預設頁面內容
  function action_form($action_id = '')
  {
  
      global $xoopsTpl, $xoopsDB;
  
      include_once XOOPS_ROOT_PATH . "/class/xoopsformloader.php";
      if ($action_id) {
          $tbl    = $xoopsDB->prefix('actions');
          $sql    = "SELECT * FROM `{$tbl}` WHERE `action_id` ='{$action_id}'";
          $result = $xoopsDB->query($sql) or web_error($sql);
          $val    = $xoopsDB->fetchArray($result);
          $op     = 'update_action';
      } else {
          $val = ['title' => '', 'action_date' => date('Y-m-d'), 'end_date' => date('Y-m-d 17:30:00'), 'enable' => '1', 'content' => ''];
          $op  = 'insert_action';
      }
  
      $form = new XoopsThemeForm('編輯活動', 'name', 'main.php', 'post', true);
      $form->addElement(new XoopsFormText('活動名稱', 'title', 40, 255, $val['title']), true);
  
      include_once XOOPS_ROOT_PATH . "/modules/tadtools/cal.php";
      $cal = new My97DatePicker();
      $cal->render();
      $action_date = new XoopsFormText('活動日期', 'action_date', 15, 255, $val['action_date']);
      $action_date->setExtra("onClick=\"WdatePicker()\"");
      $form->addElement($action_date, true);
  
      $end_date = new XoopsFormText('截止日期', 'end_date', 15, 255, $val['end_date']);
      $end_date->setExtra("onClick=\"WdatePicker({dateFmt:'yyyy-MM-dd HH:mm:ss', startDate:'%y-%M-%d 17:30:00'})\"");
      $form->addElement($end_date, true);
  
      $form->addElement(new XoopsFormRadioYN('使否啟用', 'enable', $val['enable']));
  
      include_once XOOPS_ROOT_PATH . "/modules/tadtools/ck.php";
      $ck = new CKEditor("tad_signup", "content", $val['content']);
      $ck->setHeight(350);
      $editor = $ck->render();
      $form->addElement(new XoopsFormLabel('活動內容', $editor));
  
      $form->addElement(new XoopsFormHidden('op', $op));
      $form->addElement(new XoopsFormHidden('action_id', $action_id));
      $Tray = new XoopsFormElementTray('', ' ', 'name');
      $Tray->addElement(new XoopsFormButton('', 'name', '清除', 'reset'));
      $Tray->addElement(new XoopsFormButton('', 'name', '送出', 'submit'));
      $form->addElement($Tray);
      $action_form = $form->render();
  
      $xoopsTpl->assign('action_form', $action_form);
  }
  ```
